Share 800 in the ratio 9:7.

bulgar [2K]

Answer:

The numerator '9's share is 450 and the denominator '7's share is 350.

Step-by-step explanation:

Step-1: Add the ratios:

9 + 7
16

Step-2: Divide 800 by the sum of the ratios:

800 ÷ 16
=> 50

Step-3: Multiply 50 with each ratio:

9 x 50 = 450
7 x 50 = 350

Hence, the numerator '9's share is 450 and the denominator '7's share is 350.

The equation of a line is y=x+7 give the gradient and y-intercept Help pls 17 points !!!

Angelina_Jolie [31]

The slope/ intercept form of equation of a line is

y = mx + c where m = gradient and c is the y-intercept.

y = 1x + 7

- so here the gradient = 1 and the y-intercept = 7

Use the Venn diagram to calculate probabilities.

Rudiy27

Corrected Question

These are the given probabilities. The Venn diagram is also attached. are (A) P(A|C) = 2/3

(B) P(C|B) = 8/27

(D) P(C) = 3/7

(E) P(B|A) = 13/27

Answer:

A and C

Step-by-step explanation:

$P(A|C)=\dfrac{P(A\cap C)}{P(C)}= \dfrac{14/59}{21/59}=\dfrac{14}{21}=\dfrac{2}{3}$

$P(C|B) =\dfrac{P(C\cap B)}{P(B)}= \dfrac{11/59}{27/59}=\dfrac{11}{27}\neq \dfrac{8}{27}\\\\P(A) = \dfrac{31}{59}\\\\P(C) =\dfrac{21}{59}\neq \dfrac{3}{7}\\\\P(B|A)=\dfrac{P(B\cap A)}{P(A)}= \dfrac{13/59}{31/59}=\dfrac{13}{31}\neq\dfrac{13}{27}$

From the above, only A and C are correct.
